As a new type of energy-saving light source, LED has been widely used in lighting. It is energy-saving and has a long service life. It has been favored by consumers, but how many consumers really understand the purchase of LED Wall Washer Light? Today 河南11选5分布走势图一定牛 will introduce you to the purchase considerations for LED wall washers:
1, LED brightness (MCD) is different, the price is different. LEDs for LED Wall Washer Light should meet laser class I standards.
2. Leakage current LED is a unidirectional conductive illuminator. If there is reverse current, it is called leakage, LED with large leakage current, short life and low price.
3. LEDs with the same wavelength have the same color. If the color is consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.
4. LEDs with different illumination angles have different illumination angles. Special lighting angle, the price is higher. Such as full diffusing angle, the price is higher.
